PIPE-LAYING APPAFATUS.

Application fil ed July 22, 1916. Serial mimosa.

Be it known' that I, 'WILL'IAM L. CHAP- jresldent of the borou'ghof Brooklyn of; the "city of New "York, in the State of New York,

having invented an Improvement in Pipe- Laying' Apparatus, of which the following is a specification.

'While the present invention is applicable to tools in general, and for work of different kinds, it is particularly adapted forjacking *le'adinto the joints between pipe-sections to provide a means of lead into the Itions recently ine a r calking said joints betweentheseveral sections after they have been assembledand'sealed. i 1 1 In the accompanying drawings, in which I show an embodiment of my'finvention, as

used 'in constructing a pipe harbor,

Figure l is a centralxlongitudinal section taken through a joint between two pipe sections, showing the improved tool-carrying and lead-forcing devic'e mounted thereon,

Fig. 2 is a plan view of an air motor or wrench, and its associated parts mounted in one of the seats on the band to operate a suitable implement, in this case a gib-screw, and,

Fig. 3 is aplan view of the band and its wrench-carrying seats.

Each of the pipe-sections used at the Narrows job was provided with a bellmouth at one end which terminated in a circular flange projecting laterally around the pipe. Upon and around this flange a circular band 61 was secured, with freedom for rotationfby roviding a couple of flanges 62 upon the and, one on each .side,to embrace the flange on the pipe; and roller bearings 63 were provided to eliminate friction and smooth the movement of the band. The band, as shown, was preferably made in two parts which were bolted together around the flanige on the pipe.

One ofthe objects 0 the inventlon was to enable several lead-forcing devices to be operated -at once, since in the-job at the Narrows, the head of each pipe-section was provided with thirty-two holes through which cold lead had to be forced into the shrinkage space left by the cooling of the molten lead seal. Accordingly, the band mm, a citizen of the United States, and a to the ban 'soci'ated parts (to flhave to make actually employed by me in forcingcold connecting ,joints of .pipe-sec- I r v ob, then a quarterfof a revolution e Narrows.' of New York b carrying W supporting link 65 pivotally bolted to Pawn e Ms. 2.7.1917.

was fitted with four wrench-carrying seats 6 6ft located at regular intervalsaround the clrcumference of the band, said seats being U-shaped (iF1g 3 and being rigidl 'cured.

If -four lead forcing"devices"are to be operatedtogether,"each one of these seats will be. provided witha wrench and its asbut itwill be obvious that. the"invention is 'eguallyfapplicable to one or more; such devicesyas may be desired, the'flbandTbeing "shifted each tlme to brin fthe gib screw or screws tothe parts'of i I fer'ence where the lead is to" be' forced in hus, 1f one wrench be use'dwhband will e p pes circum- I a complete "revolution before the Job ls fimsh'ed; 1f two,*a half revolution; and 1f; four are'used, as at' the F'N arrows f-t and will complete 'the'opera'tion, v i As shown in; thetdrawin gs, the'wrenchparts or umts'compr'ise a U-shaped one pivotally supporting a forked-arm 67 carrying of the seats 64 and through a bolt 66,

the wrench 68 on a pivot 69. One of these units may be secured to each seat (as will obviously be the case where four wrenches are worked together-nor where only one wrench is used, the same unit is readily capable of being secured at will to any one of the seats64. The wrench is supported between the two arms of its forked-carrier and the latter is preferably rovided with handles 70 at each end f dr lifting the wrench and otherwise manipulating 1t, the wrench being supported between one of these handles and the fulcrum of the forked-car rier.

For retaining the wrench in a particular are provided to fasten and hold the U- shaped'link or support 65 in a definite posi tion. In the job at the Narrows the holes were provided in pairs, one hole being directly back of the other (see Fig. 1), so that .both of the pipe holes when the link 65 is in the position for workbe described presently) or definite position, means such as bolts 71 71 through these two pairs of ing in the rear hole, one pair of bolt holes in the link will register with the corresponding pair in the seat and the link may be fastened and held in this position during the forcing operation by passing the iiilpper bolt 0 es. working thefirst hole the other two pairs of holes are brought into register and the link fastened in thatposition bythe upper bolt 71. Of course, as many pairs of bfolt or holes may be provided asrequired; and

working nly one line of holes such as the holes 75, around the pipe, it is obvious that the link or links 65 may be set in one definite position, that is, the link 65 need not ivot but may be rigidly secured to the and.

each side of the wrench to connect the wrenchcarrying arm 67 and its seat 64 to' hold the wrench normally in operative position with its work; for it will beunderstood that as the band revolves around the pipe, the weight of the wrench and its parts will not always be directed towardthe pipe. p

In a companion application, Serial No. 109,034 filed July 13, 19-16, I have shown and described a pipe laying system and apparatus wherein the pipe-sections are inserted one into the other to form a pipe line, and the line thus formed progressively launched into position upon a skid or launchway. In

the operation of that system, each pipe-section, after it is added to the end of the line,

rests in the upper part of the skid with its bell-mouth presented upwardly and is thenin a position for convenient application of the improved apparatus which I have described in the present application.

I do not limit myself, however, to the employment of my improved apparatus in that way, but sim ly suggest it as a convenient manner o procedure in using the same in connection with the pipe-laying system of my companion application.

' In using my improved apparatus, where four wrenches or forcing devices are employed at once, a man is employed for each device, operating the wrench through the handle or handles 70. By this means the wrench is first brought into proper position for forcing in the lead, the bolt 71 being used, if desired (as where bolt holes 72 and 73 have been provided to bring the wrench in the particular position or positions). When the first hole or pair of holes 75, .76, has been worked, the band is then shifted to bring the wrench or wrenches to the next operating position after reversing the wrenches to withdraw the gib-screws, by means of the handle-or handles.

. In view of the foregoing description, it will be understood that the word wrench has been used to denote a motor or power device for producing rotary motion and is ,wrench-carrying fork pivoted to the- U- igaaoneo not to be construed in its narrower sense; and hence the word wrench, as used in the 7 claims hereinafter,should interpreted accordingly.-

I claim as my invention: 7

A motor-carrying device comprising in combination a circular band having means to secure it to the work to be operated upon, with freedom for rotation; a motor, a motor-carrying arm having means for pivotally supporting the .motor thereonand a supporting l1l1k pivoted to the band and to whiclr the motor-carrying arm is pivotally secured, whereby the motor may be shifted with respect to the work.

4. A wrench-carrying device comprising i in combination a circular band havin means to secure it to the work to be opera upon with freedom for rotation with re-' spect to the work; a U-shaped support pivoted to the band; means to fasten and hold said support ina definite position; and ashaped support; said fork having a handle and means to pivot a wrench thereto between the two arms of the fork; the wrench being adapted to cooperate with a suitable tool.
